Low-Glycemic Index Breakfasts Increase Fat Burning During Subsequent Exercise

The Glycemic Index has been receiving a lot of media attention lately, and for good reason. In the past 20 years, it's been found that choosing lower-GI foods is not only great for your health, it also do wonders for your waistline and new research out of The Journal of Nutrition is supporting this fact. The researchers of this study have found that when Low-GI foods are consumed at breakfast, a few hours prior to exercising, more fat is burned over all in both sedentary and active individuals. In addition, the participants in the study who consumed Low-GI breakfasts also felt fuller for longer afterwards!

In case you're new to the concept, here's a quick run-down: David Jenkins, MD, PhD, a professor of nutrition at the University of Toronto noticed that different foods containing the same amount of carbohydrates could illicit extraordinarily different responses in blood sugar and insulin levels in diabetic individuals. As a result, he decided to not only find out why this happens, but also to create a system for diabetics and eventually all individuals to follow for optimal health.

Following great amounts of research, the Glycemic index was born - it's a numerical ranking of carb-containing foods based on the speed of their absorption in the bloodstream. High-GI foods are digested and absorbed very quickly, causing a rapid spike in blood sugar, followed by a tell-tale crash, usually responsible for that 3 O'clock slump! Low-GI foods are digested and absorbed more quickly, resulting in stable levels of blood sugar and insulin and giving you more steady and long-lasting energy. Not surprisingly, high-GI foods tend to be the usual suspects: refined sugars and processed grains just to name a few. Low-GI foods include most fruits and veggies, whole grains and low-fat dairy products.
